Compressed Fiber Sheets: Synonymous with Strength and Versatility

What are compressed fiber sheets?

Compressed fiber is a material manufactured by compressing cellulose fibers (paper or cardboard), often combined with other materials such as synthetic fibers, rubber, or elastomers. This combination enhances the material's strength and durability, making it suitable for industrial applications where resistance to fluids, high temperatures, or pressures is required.

The properties of these compressed fiber sheets, such as heat resistance, chemical resistance, and pressure resistance, make them ideal for use in engine gaskets, piping systems, and various sealing applications in sectors such as automotive, aviation, and manufacturing.

At JIOrings, we continuously strive to enhance and broaden our product range to meet all our customers' sealing solution needs. Therefore, we have introduced compressed fiber sheets to our product line, taking us closer to our goal of providing the most comprehensive sealing solutions on the market.

One of the primary advantages of these sheets is their resistance to high temperatures and pressures, as well as their exceptional resistance to a variety of chemicals. This makes them an excellent choice for environments requiring superior performance and increased safety. Moreover, they offer high versatility and can be cut and molded to fit various shapes and sizes, providing customized solutions for every sealing requirement.

Key Features of Compressed Fiber Sheets:

1. Strength and durability: Compressed fiber sheets are extremely robust and durable, capable of withstanding high pressures and temperatures, making them suitable for harsh industrial applications.

2. Chemical resistance: These sheets often exhibit resistance to various chemicals, including oils, fuels, and certain acids, making them suitable for environments where such elements are present.

3. Customization and versatility: Compressed fiber sheets can be easily cut and molded into different shapes and sizes, allowing for a wide range of applications. They can also be combined or laminated with other materials to enhance their properties.

Compressed fiber sheets with wire insertion:

Sometimes, compressed fiber sheets include wire insertion to enhance their mechanical and functional properties, especially in demanding applications. This wire insertion increases the mechanical strength of the sheets, prevents deformation or extrusion, and improves thermal resistance, enabling their use in high-temperature applications without degradation.

Additionally, wire insertion can increase the stiffness of gaskets obtained from these sheets, reducing the risk of breakage or damage during handling and installation, particularly in large sizes or complex shapes.

How are gaskets obtained from compressed fiber sheets?

The process of obtaining gaskets from compressed fiber sheets involves several steps:

1. Gasket design: First, the gasket design is defined, including its shape, size, and necessary holes. This design can be based on industry standards or customized according to customer requirements.

2. Sheet selection: A sheet that meets the application's specifications, such as temperature resistance, pressure, and chemical exposure, is chosen.

3. Marking and cutting: The gasket's shape is marked on the sheet, followed by cutting using various methods:

   • Manual cutting: Suitable for small series or simple designs, manual cutting employs special blades or scissors.
   • Press cutting: Used for larger productions, presses with molds or dies cut the gasket.
   • Water jet or laser cutting: Ideal for complex designs or precise production, these techniques offer precise cuts and are suitable for gaskets with intricate shapes or tight tolerances.

4. Hole punching: If the gasket requires holes (e.g., for bolts), they are punched after cutting, either manually or using machines, depending on precision and quantity requirements.

This process ensures the production of gaskets tailored to specific application needs, ensuring effective sealing and long-term performance.

Remember that choosing a gasket obtained from compressed fiber sheets over a standard rubber gasket depends on the specific application requirements. Rubber gaskets may be preferred in situations where flexibility is more critical than resistance to high temperatures or chemicals, or where cost is a determining factor.
